Modern sophisticated telecommunication devices require even more and more comprehensive testing to ensure quality. The test case amount to ensure well enough coverage of testing has increased rapidly and this increased demand cannot be fulfilled anymore only by using manual testing. Also new agile development models require execution of all test cases with every iteration. This has lead manufactures to use test automation more than ever to achieve adequate testing coverage and quality. This thesis is separated into three parts. Evolution of cellular networks is presented at the beginning of the first part. Also software testing, test automation and the influence of development model for testing are examined in the first part. The second part describes a process which was used to implement test automation scheme for functional testing of LTE core network MME element. In implementation of the test automation scheme agile development models and Robot Framework test automation tool were used. In the third part two alternative models are presented for integrating this test automation scheme as part of a continuous integration process. As a result, the test automation scheme for functional testing was implemented. Almost all new functional level testing test cases can now be automated with this scheme. In addition, two models for integrating this scheme to be part of a wider continuous integration pipe were introduced. Also shift from usage of a traditional waterfall model to a new agile development based model in testing stated to be successful.

Diplomityössä tarkasteltiin sahalaitokselle investoidun tuotannon ohjausjärjestelmän toimivuutta ja käytettävyyttä. Tutkimuksessa vertailtiin aikaisemmin suunnittelun apuna toimineita järjestelmiä uuteen ohjausjärjestelmään. Tavoitteena oli selvittää onko uuden järjestelmän sisäänajo onnistunut niin, että se tuottaisi oikeaa tietoa sahausprosessista. Tutkimuksessa tarkasteltiin myös kuinka sahan uutta ohjausjärjestelmää voitaisiin hyödyntää yrityksen myynti- ja toimitusketjun kannalta parhaiten ja huomioiden erityisesti kannattavuuslaskennallinen näkökulma. Lisäksi pohdittiin integraatiomahdollisuuksia yrityksessä käytössä oleviin muihin suunnittelujärjestelmiin. Tutkimuksen taustalla on sahateollisuuden entisestäänkin kiristynyt tilanne ja toisaalta tarve tulevaisuuden suunnitelmallisuuden parantamiseen. Kilpailussa mukana pysyminen edellyttää sahausprosessista saatavan tietomäärän keräämistä, tallentamista ja ennen kaikkea tiedon parempaa hyväksikäyttöä. Tutkimuksen kohteena ollut sahalaitos vastasi tulevaisuuden tiukentuneisiin olosuhteisiin investoimalla uuteen ohjausjärjestelmään ja uskoi siitä saatavan hyödyn auttavan heitä parantamaan sekä yksittäisten tuotteiden että koko tuotevalikoiman kannattavuutta. Ohjausjärjestelmän toivottiin tuovan todenmukaisempaa ja monipuolisempaa tietoa yrityksen suunnittelutyölle. Sahalaitoksen kannattavuuden parempi seuraaminen ja tuotevalikoiman sekä suunnittelun parempi kohdentaminen helpottuu sähköisen ohjausjärjestelmän avulla huomattavasti. Ohjausjärjestelmän kautta kannattavuuden tunnusluvut saadaan nopeammin myynti- ja toimitusketjun tietoon, poikkeamiin pystytään puuttumaan ajoissa ja yleinen tietoisuus sahausprosessista paranee. Ohjausjärjestelmän avulla mahdollistetaan entistä joustavampi koesahaus ja reklamaatioeriin porautuminen onnistuu niin ikään vaivattomammin. Yksi hyödyllinen integraatiomahdollisuus olisi SAP:n ja uuden ohjausjärjestelmän yhdistäminen, jossa hinta- ja reklamaatiotieto saataisiin yhteneväksi. Kun ohjausjärjestelmä saadaan varmuudella tuottamaan oikeaa tietoa sahausprosessista, on siitä saatava hyöty myynti- ja toimitusketjulle todellinen. Kalliin raaka-aineen entistä tehokkaampi hyödyntäminen, tuotepaletin suunnittelu ja myynnin kohdentaminen kannattavimpiin tuotteisiin, ovat tärkeä osa niitä asioita joihin järjestelmä tuo helpotusta. Tulevaisuudessa ohjausjärjestelmän jatkokehitykseen tulisi kiinnittää erityistä huomiota, jotta voitaisiin taata asiakaslähtöisyys ja kannattava tuoterakenne osana menestyksekästä liiketoimintaa.

In this thesis, the components important for testing work and organisational test process are identified and analysed. This work focuses on the testing activities in reallife software organisations, identifying the important test process components, observing testing work in practice, and analysing how the organisational test process could be developed. Software professionals from 14 different software organisations were interviewed to collect data on organisational test process and testing‐related factors. Moreover, additional data on organisational aspects was collected with a survey conducted on 31 organisations. This data was further analysed with the Grounded Theory method to identify the important test process components, and to observe how real‐life test organisations develop their testing activities. The results indicate that the test management at the project level is an important factor; the organisations do have sufficient test resources available, but they are not necessarily applied efficiently. In addition, organisations in general are reactive; they develop their process mainly to correct problems, not to enhance their efficiency or output quality. The results of this study allows organisations to have a better understanding of the test processes, and develop towards better practices and a culture of preventing problems, not reacting to them.

The purpose of this thesis is to investigate scheduled market announcements’ effects on Euro implied volatility. Timeline selected for this study ranges from 2005 to 2009. The method chosen is so-called event study approach, in which five days prior to a news announcement stand for a pre-event period, and five days after the announcement form a post-event period. Statistical research method employed is Mann-Whitney-Wilcoxon test, which examines two evenly-sized distributions’ equality, in this case the distributions being the pre- and post-event periods. Observations are based on daily data of US dollar nominated Euro at-the-money call options. Research results partially back up previous literature’s view of uncertainty increasing prior to the news announcement. After the exact contents of the news is public, uncertainty levels measured by implied volatility tend to lower.

This paper presents the design for a graphical parameter editor for Testing and Test Control Notation 3 (TTCN-3) test suites. This work was done in the context of OpenTTCN IDE, a TTCN-3 development environment built on top of the Eclipse platform. The design presented relies on an additional parameter editing tab added to the launch configurations for test campaigns. This parameter editing tab shows the list of editable parameters and allows opening editing components for the different parameters. Each TTCN-3 primitive type will have a specific editing component providing tools to ease modification of values of that type.

CHARGE syndrome, Sotos syndrome and 3p deletion syndrome are examples of rare inherited syndromes that have been recognized for decades but for which the molecular diagnostics only have been made possible by recent advances in genomic research. Despite these advances, development of diagnostic tests for rare syndromes has been hindered by diagnostic laboratories having limited funds for test development, and their prioritization of tests for which a (relatively) high demand can be expected. In this study, the molecular diagnostic tests for CHARGE syndrome and Sotos syndrome were developed, resulting in their successful translation into routine diagnostic testing in the laboratory of Medical Genetics (UTUlab). In the CHARGE syndrome group, mutation was identified in 40.5% of the patients and in the Sotos syndrome group, in 34%, reflecting the use of the tests in routine diagnostics in differential diagnostics. In CHARGE syndrome, the low prevalence of structural aberrations was also confirmed. In 3p deletion syndrome, it was shown that small terminal deletions are not causative for the syndrome, and that testing with arraybased analysis provides a reliable estimate of the deletion size but benign copy number variants complicate result interpretation. During the development of the tests, it was discovered that finding an optimal molecular diagnostic strategy for a given syndrome is always a compromise between the sensitivity, specificity and feasibility of applying a new method. In addition, the clinical utility of the test should be considered prior to test development: sometimes a test performing well in a laboratory has limited utility for the patient, whereas a test performing poorly in the laboratory may have a great impact on the patient and their family. At present, the development of next generation sequencing methods is changing the concept of molecular diagnostics of rare diseases from single tests towards whole-genome analysis.
